I took a special copper Fireflies X4 and modded it with a special LED, the 90 CRI SFT25R 5700k from Kaidomain. These LEDs are everything I had hoped. Not greenish and throwy, they very much remind me of the tint of the Yinding 5050 95 CRI.

I also stole the optics from a Sofirn IF25A, which has much better optics than any of the stock ones that come with the X4. No other Sofirn or Wurkkos (not even the TS25) seem to have the magic optics from the IF25A. They are similar to the throwy optics of the X4, but are frosted only over the center spill region, not the entire optic like the floodier X4 optics, resulting in a cleaner beam with a strangely fatter hotspot without harming throw at all.
